All of the above

Explanation:

The coelomate is a term used for a very wide range of animals. Basically the coelomates have a body cavity that is known as coelom. The coelom includes a compete lining which is known as peritonium which derives from one of the three primary tissue layers, the mesoderm. The coelomates include the chordates, arthropods, mollusks, and echinoderms. The fish falls into the category of chordates, the shrimp into the category of mollusks, and the humans into the category of arthropods, so all of them can be classified as coelomates.
